Arthemis d’Cannith

Great Mark of Making. As a bonus action, Arthemis d'Cannith uses the power of his dragonmark to bring forth a clockwork shadow made of available metallic materials
in the area. The clockwork shadow appears in a square adjacent to Arthemis. Arthemis can control one clockwork shadow automatically. If he summons a second one, he must maintain concentration. If he loses concentration, any existing clockwork shadows disassemble instantly.

Rapier. Melee Weapon Attack: +6 to hit, reach 5 ft., one target. Hit: 8 (1d8 + 4) piercing damage.

Construct Sacrifice. If Arthemis d'Cannith is hit, he can use
his reaction to redirect the attack to a clockwork shadow he
created adjacent to him.
